Update: Dylan Redwine, who vanished on November 19 during a court-ordered visit to his father's home in the Vallecito Lake area, continues to be the subject of a massive search. And while clues about his whereabouts remain elusive (see earlier coverage below), new developments have surfaced in the case. Law enforcers have concluded he didn't run away -- and his father has stepped forward for the first time since his ex-wife pointed a finger at him.

While representatives of the La Plata County Sheriff's Office aren't saying why they believe Dylan, thirteen, is not a runaway, investigators are no longer treating this theory as probable. Instead, they're focusing on canvassing the Vallecito area with the aid of an updated flier that sports a new tip line number. Here it is:

Meanwhile, friends, family members and loved ones of Dylan staged a candlelight vigil in Bayfield, near Durango in southwestern Colorado -- and among those who turned up for the event was Mark Redwine, the boy's father.

Mark Redwine.

As we've reported, Mark and Elaine Redwine, Dylan's mom, divorced in 2007, with Dylan and Elaine moving to the Colorado Springs area last year. In an interview with ABC News on view below, Elaine suggested that Mark might have played a role in Dylan vanishing, saying he may have tried to "remove Dylan from the situation. You know, like, 'If I can't have him, nobody will.'

"I was married to Mark for a lot of years, and I know the way he reacts to things," she went on. "If Dylan maybe did or said something that wasn't what Mark wanted to hear, I'm just afraid of how Mark would have reacted."

Last night, in an interview with Fox31, Mark didn't directly address these insinuations, but he made it clear he's eager for his son's return. "He needs to come home and that's what everyone wants for him," he told the station, adding, "My focus is on Dylan and what he needs from us.... That's all I have to say."

The folks behind the Find Missing Dylan Redwine Facebook page continue to share regular updates about the case -- including this post from six hours ago at this writing: "Because all of you are working so hard over 18,000 peeps around the world are seeing Dylan's face! Let's make it millions! We want to bring Dylan home!"

The Facebookers have been lobbying for CNN's Nancy Grace to pick up the story, and she has, offering a number of tweets about Dylan late yesterday -- this one among them:

It's been a long 10 days and we miss you so much. You would have been so proud of Cory last night at your vigil, I was. He misses you so much, we hope that you can at least see these and know how much we all love you! The community came out last night and prayed for you, it was beautiful. Your friends talked about you being the class clown! Sounds like spanish class was your favorite class to be the clown in. Unicorn huh? Funny, funny stuff. I hope you are warm somewhere, that you have good food and you are being nourished. We all go to bed thinking about you, I don't think anyone really sleeps right now, but we get up in the morning thinking about you again, all day~everyday~ until you come home. Love you buddy

I'm posting your favorite song for you again, every night until you come home... it's the acoustic version this time, just thought I would change it up a bit for you.

Below, see four videos, including the latest Fox31 report, featuring Mark Redwine's comments; a clip assembling photos from the candlelight vigil; a 7News report; and the song mentioned in the friend's Facebook post above -- "Blurry" by Puddle of Mudd. That's followed by our previous coverage.

Continue to read our earlier coverage about the disappearance of Dylan Redwine.

Original post, 9:29 a.m. November 27: Last month, the abduction and murder of Jessica Ridgeway, a ten year old from Westminster, became a tragic national story. Mere weeks later, the disappearance of Dylan Redwine, thirteen, who vanished in Southwestern Colorado on November 19, is also receiving coast-to-coast attention -- but his loved ones are praying for a happier ending.

The basics about the case: Dylan's mother, Elaine, and father, Mark, divorced in 2007, with Dylan moving with his mom from Southwestern Colorado to Colorado Springs this past year. On November 18, however, Dylan traveled to the community of Vallecito, not far from Durango, to spend the Thanksgiving holiday with his dad.

The next day, Mark told representatives of the La Plata Sheriff's Office that he left home around 7:30 a.m. to run some errands, and upon his return four hours later, Dylan was gone. And he hasn't been seen since then.

Since then, a slew of theories have surfaced. Some believe Dylan ran away. Others fear he split with the intention of rendezvousing with friends, only to be abducted. And Elaine has raised questions about Mark, sharing with ABC News her suspicion that her ex-husband may have tried to "remove Dylan from the situation. You know, like, 'If I can't have him, nobody will.'

"I was married to Mark for a lot of years, and I know the way he reacts to things," she went on. "If Dylan maybe did or said something that wasn't what Mark wanted to hear, I'm just afraid of how Mark would have reacted."

Responding to these implications, Mark Redwine told 7News that Elaine was making the situation "more than it needs to be" before adding that he wanted to avoid lashing out at her.

In the meantime, the Find Missing Dylan Redwine Facebook page is providing up-to-date information about the search and affiliated events, including a prayer and caring vigil slated for 6 p.m. tonight in Bayfield. Also included are photos, such as these shots of the search for Dylan in the area around Vallecito Lake on Sunday....

...and this image of Dylan's friends distributing flyers like the one seen above:

Today, no searches at the lake are being conducted -- but a recently posted Facebook note urges folks not to leap to conclusions. It reads:

The search for Dylan has not been called off. Investigators are still exploring every option, they have simply stopped looking in the lake. The community is still searching for Dylan and La Plata County officials are now being assisted by several federal [agencies] from around the country. Please be discerning when you read the news, while I know most people try to get a close to the truth as possible reporters can not help but try to sensationalize things to sell their news.
